Most of the parts are proprietary, so if you bork a derailleur you get to wait 6-8 weeks for a replacement from the UK

it isn't though

it's more like having your friend write an essay for you, except the friend is an impressionable 5 year old with a PhD

Sheldon was a wealth of information when I first started tinkering on my vintage 3-speed back in 2007. I would pore over these simple pages for hours in my dorm at college instead of studying. That led to dropping out and working in the bike industry for almost 10 years. It was a great preparation in problem solving and systems-oriented thinking before I got into programming.

For PBP2027 you have all of 2026, as well as 2027 leading up to registration, to complete the required BRMs.

I'm riding my qualifying 300k tomorrow!

Henry is one of the most cutting edge designers out there today in my opinion. Check out his other sites.

I'm currently incubating a sick twisted fantasy to run a handbuilt bicycle wheelbuilding store. If you asked me this question 20 years ago, the answer would be music teacher.

> It takes 23 minutes and 15 seconds to regain deep focus after a context switch (UC Irvine).

According to the cited study, interruptions (especially "related" ones) actually result in people working harder and faster.

Interesting that the PS5 has been implicated - does this mean that there is an opportunity to jailbreak firmware again?

I'm convinced bicycle commuting is what's going to make my 8:30-5:30 bearable. Hope I'm right.

It's a long expired domain that originally belonged to that SJSU professor, I doubt he will ever update the links on these articles. That doesn't negate the value of the article itself.

Who cares if WP Engine disables revisions. Wordpress.com disables the use of plugins, arguably a core feature of WordPress, unless you pony up $300 a year for a "Business" tier account.

Complete bicycle manufacturers usually make these specification lists public in online and print catalogs. Component-level repair, as in many other fields, requires more specialized knowledge and a parts list is rarely practical nor helpful.

Seatposts support hundreds of pounds of human flesh also, so the weight usually isn't the concern. But if your bike looks like more of a motorcycle, it's probably not going into my work stand.

On the point about the power cable, this is more directed at hub Drive motors. If I can't disconnect your motor to remove your wheel, I'm not going to fix your flat tire.

If your hoods aren't absolutely disintegrating into goo, a little talc powder goes a long way towards getting rid of the stickiness.

I had 3 simple questions to decide if an e-bike went in my stand: 1.) Does the frame use a seatpost? 2.) Are there any frayed or broken wires? 3.) Is the power cable to the motor removable?

Bottom bracket fussing is a tale as old as time. I have a bike from 1983 with an original Suntour bottom bracket. It even uses cartridge bearings! But the spline pattern for the cups is proprietary and the tool has long been out of production.
